While this book is interesting it does contain at least one missconception. As Ellis has pointed out in arXiv:astro-ph/0603266 v1; Susskind's claim that evidence for the existence and nature of ‘pocket universes’ in a multiverse would be available via detailed study of the Cosmic Blackbody Background Radiation arrises from confusion between the nature of a particle horizon and an event horizon in cosmology.
